cricketgirlsadjustingUsing the Inquiry Wheel – Crickets

Standards

 Science/Engineering: K-2 ETS1-1 Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

 Engineering: K-2 ETS1-2 Develop a physical model to solve a problem

 Engineering: K-2 ETS1-3 Analyze data from tests of different objects attempting to solve the same problem as to strengths and weaknesses

CCSS.Math.Content.K.MD.B.3
Classify objects into given categories; count the numbers of objects in each category and sort the categories by count

WOW

A container of 10 crickets purchased from the pet store. Put them in the middle of a large under-bed tray [about 2 ft by 3 ft by 8 in. high] for the observation and experiment. Keep in a terrarium when not being tested.

TOOLS NEEDED

Child-friendly stop watches; paper scraps, markers, scissors, staplers

SCIENCE INQUIRY PROCESS

 Observe: Have children gather around the bin and ask them to safely observe the crickets using all the appropriate senses.

  • Visual: What do they look like? What colors are they? How big are they? What body parts do you see?
  • Hearing: Do they make any sounds?
  • Smell: Do they give off an odor?
  • Touch: Have children take turns holding a cricket. How does it feel? How does it move?
  • Taste: Are they something we want to taste? Why or why not?

Ask Questions Have children brainstorm questions and record on a chart . Examples:

  • Are they alive? How do we know?
  • Can they see?
  • What do they eat?
  • Where do they live?
  • Do they like light or dark places?

 Make Predictions

  • They can see because they have what look like eyes.
  • They like dark because they keep trying to crawl underneath other.
  • If we make dark places will they go inside?
  • How long will they stay inside?

 Test

  • First, engineer dark places “houses” using different colored paper, different forms, different openings. Affix together using staples. Limitation: No Tape. Tape might hurt a cricket that gets stuck in it. (Engineering)
  • Use color and form to create a space appealing to the crickets and easily identifiable as your own. (Arts)
  •  Time how long they stay inside using a stop watch. (Mathematics)

 Record Results

  •  Record number of crickets inside and outside every minute on a checklist
  • If a cricket enters a house record which house and how long it stays inside on a chart.

Compare

  • Did crickets go inside or not?
  • Graph how long they stayed in the different houses. (Mathematics)

 Come to a Conclusion

  • Did crickets prefer the houses or being out in the open?
  • Which type of house did they prefer the most?

 Sharing

  • Display a finished graph.
  • Display the house designs and discuss how they functioned  (Arts: Responding)
  • Show photographs/videos of cricket behavior during test (Technology)

 New Questions

  •             Did the size of the house make a difference?
  •             What would the crickets do in the dark?
  •             What would happen if you put food inside the houses?
